knock going over speed bumps 1 Year, 1 Month ago Karma: 106
How long is a piece of string - just looking for some direction on this

Ive noticed recently a knock when I go over the odd speed bump - drivers side rear intial thoughts

Initial line of thought is:

Drop links
Anti roll bar bushes
Top Mounts

Any ideas?

Could be anyone of the things u mentioned, I had a knocking sound going over bumps before and turned out to be a wheel bearing,hope u find the problem nothing worse than annoying sounds coming from your car and trying to pinpoint them

I had a similar issue a couple of years back. Turns out it was just the top nut on one of the rear struts had come loose. No idea how but a quick tighten and everything was back to rosey

Let us know how you get on.

If you're suffering from lag, you're either in the wrong gear or the wrong car!

....solved!

While car is up on the stands for coolant change I changed out the drop links to solved the knocking on passenger left rear

First side took 15 mins

...thanks to this beast of a yoke.....available on amazon for £66

Old one was pretty tired and leaking at bottom boot

I dont know what happened with this side but I noticed it had fresher nut on the end of it that was easily shifted

Look what the last butcher done to it - its lasted 6 years as I haven't touched these since I owned here

The other side (working one) wasn't so easy

The nuts cracked off handy enough with the impact gun but the allen key centre jst crumbled

Got a vice grips and plumbers pliers in there behind and shifted it eventually albeit about 45 mins later -

New one in torqued to 49nm

Old ones for the skip

Intial opinions assuming the ones below are genuine toyota parts the blueprint appear to be vastly superior quality wise to what came out

Blue print using a 17mm nut vs Toyotas 14mm FYI :cool:
